This paper presents results of topic modeling and network models of topics using the ICCS corpus, which contains domain-specific (computational science) papers over sixteen years (a total of 5695 papers). We discuss topical structures of ICCS, how these topics evolve over time in response to the topicality of various problems, technologies and methods, and how all these topics relate to one ano...

Recent advances in methods and techniques enable us to develop an interactive overlay to the global map of science based on aggregated citation relations among the 9,162 journals contained in the Science Citation Index and Social Science Citation Index 2009 combined. The resulting mapping is provided by VOSViewer. We first discuss the pros and cons of the various options: cited versus citing, m...

Community structure detection has proven to be important in revealing the underlying organisation of complex networks. While most current analyses focus on static networks, the detection of communities in dynamic data is both challenging and timely. An analysis and visualisation procedure for dynamic networks is presented here, which identifies communities and sub-communities that persist acros...

Research collaboration plays an important role in scientific productivity and academic innovation. Multi-institutional collaboration has become a vital approach for integrating multidisciplinary resources and expertise to enhance biomedical research. There is an increasing need for analyzing the effect of multi-institutional research collaboration. In this paper, we present a collaboration anal...

The recent explosive growth of live-streaming, particularly video game streaming on Twitch.tv, has led to the development of young communities in a diverse and frequently evolving virtual social space. This study is a Social Network Analysis that aims to uncover how communities are interlocked based on attributes such as Community membership and stream style/type. Additionally, the network geog...

The increased usage of information technologies in educational tasks resulted in high volume of data, exploited to build analytical systems that can provide practical insight in the learning process. In this paper, we propose a method of running social network analysis on multiple data sources (academic years, communication tools). To achieve this, the collected data that describe social intera...
